Exchange Online Advanced Threat Protection

With Safe Attachments, you can prevent malicious attachments from impacting your messaging environment, even if their signatures are not known. All suspicious content goes through a real-time behavioral malware analysis that uses machine learning techniques to evaluate the content for suspicious activity. Unsafe attachments are sandboxed in a detonation chamber before being sent to recipients. The advantage is a malware free and cleaner inbox with better zero-day attack protection.

Protect your environment when users click malicious links

Exchange Online Protection provides protection against malicious links by scanning content. Safe Links expands on this by protecting your environment when users click a link. While the content is being scanned, the URLs are rewritten to go through Office 365. The URLs are examined in real time, at the time a user clicks them. If a link is unsafe, the user is warned not to visit the site or informed that the site has been blocked. Reporting is available, so administrators can track which users clicked a link and when they clicked it.
